1 00:00:00,000 --> 00:00:02,580 Hello everyone and welcome to a new section. 2 00:00:02,579 --> 00:00:04,349 In this section I'm gonna be showing you 3 00:00:04,350 --> 00:00:06,120 how you can turn your render engine from 4 00:00:06,120 --> 00:00:08,070 cycles over to EV and 5 00:00:08,070 --> 00:00:10,790 convert your whole scene into that render engine. 6 00:00:10,785 --> 00:00:13,095 Av is quite different from cycles, 7 00:00:13,095 --> 00:00:15,635 lighting, glass, reflections. 8 00:00:15,630 --> 00:00:17,420 All of that works much differently. 9 00:00:17,415 --> 00:00:19,925 And I'm going to be talking about how it works and how 10 00:00:19,920 --> 00:00:22,910 to optimize your scene to make it look really nice. 11 00:00:22,905 --> 00:00:24,965 So let's go ahead and get started. 12 00:00:24,960 --> 00:00:26,490 Here is our final scene, 13 00:00:26,490 --> 00:00:28,290 it using the Cycles Render Engine. 14 00:00:28,290 --> 00:00:29,940 And before you change anything, 15 00:00:29,940 --> 00:00:31,140 make sure you save it as 16 00:00:31,140 --> 00:00:32,900 a new blend file so you can 17 00:00:32,895 --> 00:00:35,615 always go back to your one in cycles. 18 00:00:35,619 --> 00:00:37,729 So with this blend file selected, 19 00:00:37,730 --> 00:00:39,550 I'm going to press Control Shift and 20 00:00:39,545 --> 00:00:42,065 S to save it as a new blender file. 21 00:00:42,065 --> 00:00:44,635 I'm going to call it EV Tutorial 22 00:00:44,630 --> 00:00:48,160 3 because I've tried to record this three times so far. 23 00:00:48,155 --> 00:00:51,335 And once you've done that, you can click on Save As. 24 00:00:51,335 --> 00:00:53,575 Now that we've saved it as a new blender file, 25 00:00:53,570 --> 00:00:56,330 we can go to the EV render engine and not 26 00:00:56,330 --> 00:00:57,410 have to worry about messing 27 00:00:57,410 --> 00:00:59,480 anything up in these cycles version. 28 00:00:59,480 --> 00:01:02,020 So let's switch over to EV. 29 00:01:02,015 --> 00:01:03,955 Let's take a look at our scene by hitting 30 00:01:03,950 --> 00:01:06,350 Z and going into rendered view. 31 00:01:06,350 --> 00:01:08,420 This might take a couple of minutes 32 00:01:08,420 --> 00:01:10,370 or you can see there it was pretty quick. 33 00:01:10,370 --> 00:01:13,760 And you can see our scene doesn't really look that great. 34 00:01:13,760 --> 00:01:15,380 The windows are currently not 35 00:01:15,380 --> 00:01:17,680 working and we'll fix that in just a second. 36 00:01:17,675 --> 00:01:19,135 But first off, I wanted to 37 00:01:19,130 --> 00:01:21,020 fix some of the Render Settings. 38 00:01:21,020 --> 00:01:22,370 I'm going to zoom in over here 39 00:01:22,370 --> 00:01:24,110 and show you what some of these do. 40 00:01:24,110 --> 00:01:26,660 First off, we're going to turn on ambient inclusion. 41 00:01:26,660 --> 00:01:28,640 You can see this adds a little bit of darkness 42 00:01:28,640 --> 00:01:30,860 around the corners of all of the objects. 43 00:01:30,860 --> 00:01:32,540 You can control the strength of this 44 00:01:32,540 --> 00:01:34,240 by turning up the factor amount. 45 00:01:34,235 --> 00:01:35,695 If you bring those up to three, 46 00:01:35,690 --> 00:01:37,300 you can see it's a lot darker. 47 00:01:37,295 --> 00:01:39,815 I'm just going to leave it at a value of one. 48 00:01:39,815 --> 00:01:42,445 You can also turn on a bloom and this is going to need 49 00:01:42,440 --> 00:01:44,810 to add a glow around the lights. 50 00:01:44,810 --> 00:01:46,160 So if I come over to here, 51 00:01:46,160 --> 00:01:47,600 you can see with it off, 52 00:01:47,600 --> 00:01:48,760 there is no glow. 53 00:01:48,755 --> 00:01:49,825 But with that turned on, 54 00:01:49,820 --> 00:01:52,370 it adds a nice glow around that area, 55 00:01:52,370 --> 00:01:53,810 which is pretty nice. 56 00:01:53,810 --> 00:01:56,030 You can control the strength of this bloom by 57 00:01:56,030 --> 00:01:58,430 turning up the intensity slider. 58 00:01:58,430 --> 00:02:01,250 I'm just going to leave it at the default settings. 59 00:02:01,250 --> 00:02:03,410 One very important setting that we need to 60 00:02:03,410 --> 00:02:05,470 turn on is a screen space. 61 00:02:05,465 --> 00:02:08,255 Reflections. Make sure that is enabled 62 00:02:08,255 --> 00:02:09,415 and that will change how 63 00:02:09,410 --> 00:02:11,680 your reflections work in your entire scene. 64 00:02:11,675 --> 00:02:13,165 You can see with it off there 65 00:02:13,160 --> 00:02:14,650 is no reflection in the water, 66 00:02:14,645 --> 00:02:17,815 but with it turned on, we now have reflection. 67 00:02:17,810 --> 00:02:19,910 Open up this panel and make 68 00:02:19,910 --> 00:02:22,060 sure refraction is also turned on. 69 00:02:22,055 --> 00:02:23,665 This will allow us to modify 70 00:02:23,660 --> 00:02:25,310 the glass materials we can actually 71 00:02:25,310 --> 00:02:28,670 see through it and then also turn off half raise traced. 72 00:02:28,670 --> 00:02:29,800 So we're actually using 73 00:02:29,795 --> 00:02:33,035 the full resolution on all of the rays. 74 00:02:33,220 --> 00:02:36,350 Next up we're going to open up these shadows. 75 00:02:36,350 --> 00:02:39,050 The cube size is currently set to five at 12. 76 00:02:39,050 --> 00:02:42,080 This will give us a kind of low resolution shadow. 77 00:02:42,080 --> 00:02:45,620 So let's bring that up to a value of 248. 78 00:02:45,620 --> 00:02:47,030 That's just going to increase 79 00:02:47,030 --> 00:02:49,130 the resolution of all of our shadows. 80 00:02:49,130 --> 00:02:53,540 The cascade side, I'm also going to bring up to 2048. 81 00:02:53,540 --> 00:02:57,020 And that will also make and that will also help with 82 00:02:57,020 --> 00:02:58,670 the resolution of the shadows 83 00:02:58,670 --> 00:03:00,580 and making sure everything looks good. 84 00:03:00,575 --> 00:03:03,475 You can also turn on high bit depth shadows 85 00:03:03,470 --> 00:03:06,410 and that will increase the resolution as well. 86 00:03:06,410 --> 00:03:09,170 The indirect lighting we will cover later, 87 00:03:09,170 --> 00:03:10,910 but for now we're going to close that off. 88 00:03:10,910 --> 00:03:13,040 And I think everything else is good to go. 89 00:03:13,040 --> 00:03:15,400 We have medium, high contrast in the color management. 90 00:03:15,395 --> 00:03:17,915 So now let's work on the materials. 91 00:03:17,915 --> 00:03:20,095 I'm going to select the window material 92 00:03:20,090 --> 00:03:22,820 first and then go over to the Material tab. 93 00:03:22,820 --> 00:03:25,610 Make sure you have the glass material selected. 94 00:03:25,609 --> 00:03:27,529 And how this works is we need to 95 00:03:27,530 --> 00:03:29,990 turn on its screen space refraction. 96 00:03:29,990 --> 00:03:31,730 And then we'll be able to see 97 00:03:31,730 --> 00:03:34,750 inside our house as you can see there. 98 00:03:34,745 --> 00:03:38,125 And that is basically all we really need to do. 99 00:03:38,120 --> 00:03:39,590 As with the other materials. 100 00:03:39,590 --> 00:03:41,770 We're going to select our pool water, 101 00:03:41,765 --> 00:03:43,905 turn on screen at space refraction. 102 00:03:43,909 --> 00:03:46,009 And then we should be able to see inside ice, 103 00:03:46,010 --> 00:03:47,930 you can see the other material 104 00:03:47,930 --> 00:03:50,030 that we need to fix is all of the plants. 105 00:03:50,030 --> 00:03:53,260 You can see since they're using a transparent texture, 106 00:03:53,255 --> 00:03:56,525 is giving us a black outline over every single leaf. 107 00:03:56,525 --> 00:03:59,395 So what we need to do is selected that material. 108 00:03:59,390 --> 00:04:01,540 We have the leaves material selected. 109 00:04:01,535 --> 00:04:03,055 Underneath the blend mode, 110 00:04:03,050 --> 00:04:05,420 we need to select Alpha hashed. 111 00:04:05,420 --> 00:04:06,980 And that's going to get rid of 112 00:04:06,980 --> 00:04:09,470 that transparency and give us that this effect, 113 00:04:09,470 --> 00:04:11,090 which looks a lot better. 114 00:04:11,090 --> 00:04:12,590 Let's do the same thing for 115 00:04:12,590 --> 00:04:14,360 this object over here inside the house. 116 00:04:14,360 --> 00:04:16,270 Let's go ahead and select it. 117 00:04:16,265 --> 00:04:17,705 And then on the blend mode, 118 00:04:17,705 --> 00:04:20,255 set it over to Alpha hashed. 119 00:04:20,255 --> 00:04:22,165 Finally, it will come up here to 120 00:04:22,160 --> 00:04:24,380 the big tree and do the same thing. 121 00:04:24,380 --> 00:04:27,080 And you might think to switch it over to alpha blended. 122 00:04:27,080 --> 00:04:29,360 But the problem with that is it doesn't 123 00:04:29,360 --> 00:04:32,110 really work with and multi-layer transparency. 124 00:04:32,105 --> 00:04:35,105 You can see here, if I switch it over to alpha blend, 125 00:04:35,105 --> 00:04:37,345 it's not going to display those at all. 126 00:04:37,340 --> 00:04:39,890 It's only going to display the trees. 127 00:04:39,890 --> 00:04:41,800 So switching it over to 128 00:04:41,795 --> 00:04:44,335 Alpha hat allows other transparent objects. 129 00:04:44,330 --> 00:04:45,380 You can actually see through 130 00:04:45,380 --> 00:04:46,910 them and see that transparency, 131 00:04:46,910 --> 00:04:48,520 which is what we want. 132 00:04:48,515 --> 00:04:51,005 And that looks much better. 133 00:04:51,005 --> 00:04:52,645 You also might notice that we have 134 00:04:52,640 --> 00:04:54,580 a lot of light bleed all over the place, 135 00:04:54,575 --> 00:04:56,915 especially over here in the top right. 136 00:04:56,915 --> 00:04:59,305 Eb is known for rendering light bleed and 137 00:04:59,300 --> 00:05:01,640 there are a couple of ways to fix that. 138 00:05:01,640 --> 00:05:04,480 Let's go ahead and select the lab in our scene. 139 00:05:04,475 --> 00:05:06,475 And the first thing that we need to do to 140 00:05:06,470 --> 00:05:08,750 help prevent that light bleed is to 141 00:05:08,750 --> 00:05:13,300 open up the shadow and then turn on at contact shadows. 142 00:05:13,295 --> 00:05:15,595 What contact shadows does is it basically 143 00:05:15,590 --> 00:05:17,660 takes the light and where there 144 00:05:17,660 --> 00:05:19,690 is a shadow and then adds a little bit 145 00:05:19,685 --> 00:05:22,085 of a shadow really close to that edge. 146 00:05:22,085 --> 00:05:25,135 That edge is determined by the distance slider. 147 00:05:25,130 --> 00:05:26,360 So if I drag this up, 148 00:05:26,360 --> 00:05:28,640 that might help prevent a little bit, 149 00:05:28,640 --> 00:05:30,260 but you can see it's still there. 150 00:05:30,260 --> 00:05:32,270 So another way to fix light bead is 151 00:05:32,270 --> 00:05:34,150 to add some thickness to your object. 152 00:05:34,145 --> 00:05:35,695 So we're gonna go ahead and do that, 153 00:05:35,690 --> 00:05:37,310 select your main A-frame of 154 00:05:37,310 --> 00:05:39,320 the house and go over to the modifier, 155 00:05:39,320 --> 00:05:41,270 tap the thickness slider 156 00:05:41,270 --> 00:05:43,880 here and the solidify modifier we're going to bring up. 157 00:05:43,880 --> 00:05:45,230 First though I'm going to set 158 00:05:45,230 --> 00:05:47,000 the offset all the way up to one. 159 00:05:47,000 --> 00:05:49,550 So instead of extending inside the house, 160 00:05:49,550 --> 00:05:50,960 the thickness is actually going to 161 00:05:50,960 --> 00:05:52,960 go on the outside of the house. 162 00:05:52,955 --> 00:05:54,785 So for the thickness slider, 163 00:05:54,785 --> 00:05:58,565 I'm going to set that up to 0.2 and enter. 164 00:05:59,080 --> 00:06:02,450 And hopefully that will prevent any light bleed that's in 165 00:06:02,450 --> 00:06:04,970 these corners will do the same thing over here. 166 00:06:04,970 --> 00:06:06,880 We're going to select this plane 167 00:06:06,875 --> 00:06:08,225 or this object right here. 168 00:06:08,225 --> 00:06:09,745 And underneath the thickness, 169 00:06:09,740 --> 00:06:12,290 we're going to go up two instead of point 170 00:06:12,290 --> 00:06:13,460 2 because that's a bit too 171 00:06:13,460 --> 00:06:15,080 much on this side of the house. 172 00:06:15,080 --> 00:06:18,980 Let's go up to 0.15 and Enter. 173 00:06:18,980 --> 00:06:21,260 You can see inside that it's 174 00:06:21,260 --> 00:06:22,820 clipping into that object now. 175 00:06:22,820 --> 00:06:24,110 So on the offset, 176 00:06:24,110 --> 00:06:26,820 let's try a value of 0. 177 00:06:27,270 --> 00:06:29,580 That will look a little bit better. 178 00:06:29,575 --> 00:06:30,645 And as you can see though, 179 00:06:30,640 --> 00:06:32,910 there is still some light bleed right there. 180 00:06:32,905 --> 00:06:36,235 Another way to fix that is to lower the lights. 181 00:06:36,234 --> 00:06:39,144 So what we can do is select of those lights right here. 182 00:06:39,145 --> 00:06:41,205 I'll select this one as well. 183 00:06:41,200 --> 00:06:43,630 The select those objects will go back 184 00:06:43,630 --> 00:06:46,440 into rendered view and drag this underneath. 185 00:06:46,435 --> 00:06:48,615 And as you can see, once we drag it underneath, 186 00:06:48,610 --> 00:06:50,700 that light is now gone. 187 00:06:50,695 --> 00:06:52,485 Let's go back into camera view 188 00:06:52,480 --> 00:06:53,590 and double-check the rest of 189 00:06:53,590 --> 00:06:54,760 the scene and I think everything 190 00:06:54,760 --> 00:06:57,070 else is looking pretty good. 191 00:06:57,070 --> 00:06:59,820 Now let's talk about indirect lighting. 192 00:06:59,815 --> 00:07:01,695 Indirect lighting allows there to be 193 00:07:01,690 --> 00:07:04,020 light bounces in EV, at the moment, 194 00:07:04,015 --> 00:07:05,925 there is no light bounces and that's why 195 00:07:05,920 --> 00:07:08,930 the whole scene looks very plain and boring. 196 00:07:08,925 --> 00:07:11,635 So to add light bounces and EV, 197 00:07:11,630 --> 00:07:13,420 you need to add in a new object. 198 00:07:13,415 --> 00:07:14,875 We're going to press Shift a and go 199 00:07:14,870 --> 00:07:16,220 over to the light probe 200 00:07:16,220 --> 00:07:19,550 and then add in any radiance volume object. 201 00:07:19,549 --> 00:07:21,109 With this object selected, 202 00:07:21,110 --> 00:07:23,900 we need to scale it up to match the rest of the scene. 203 00:07:23,900 --> 00:07:27,040 I'm going to go into top view by hitting seven. 204 00:07:27,035 --> 00:07:29,275 And then I'm going to press S to scale and 205 00:07:29,270 --> 00:07:31,940 scale it up to fit the entire house. 206 00:07:31,940 --> 00:07:33,920 Just like this. 207 00:07:33,920 --> 00:07:36,050 So right about there looks pretty good. 208 00:07:36,050 --> 00:07:38,660 You want to make sure that this is as small as it can be 209 00:07:38,660 --> 00:07:40,220 because it's going to take a long time 210 00:07:40,220 --> 00:07:41,900 to bake the indirect lighting. 211 00:07:41,900 --> 00:07:44,600 We're gonna go into front view now and scale 212 00:07:44,600 --> 00:07:47,470 this along the z-axis until it fits the house. 213 00:07:47,465 --> 00:07:49,045 So right about there and then we'll 214 00:07:49,040 --> 00:07:50,720 drag it down right about there. 215 00:07:50,720 --> 00:07:52,820 Looks pretty good. 216 00:07:52,820 --> 00:07:55,190 Let's go over to the settings and we're 217 00:07:55,190 --> 00:07:56,840 going to talk about the resolution. 218 00:07:56,840 --> 00:07:58,390 The resolution is how good at 219 00:07:58,390 --> 00:08:00,340 the indirect lighting will work. 220 00:08:00,335 --> 00:08:02,065 You can see with the screenshots 221 00:08:02,060 --> 00:08:03,440 so that a low resolution, 222 00:08:03,440 --> 00:08:05,990 there's not a very high-quality look 223 00:08:05,990 --> 00:08:08,840 to the bounces of light with a high resolution, 224 00:08:08,840 --> 00:08:10,130 it looks a lot better. 225 00:08:10,130 --> 00:08:11,660 So along the z-axis, 226 00:08:11,660 --> 00:08:12,830 I'm going to leave it at four, 227 00:08:12,830 --> 00:08:14,260 but along the x and the y, 228 00:08:14,255 --> 00:08:16,775 I'm going to bring it up to a value of eight. 229 00:08:16,775 --> 00:08:18,565 You also don't want to go too 230 00:08:18,560 --> 00:08:20,450 high with these values because sometimes it will 231 00:08:20,450 --> 00:08:21,890 look a little bit weird and you'll 232 00:08:21,890 --> 00:08:24,160 have more light bead than usual. 233 00:08:24,155 --> 00:08:27,235 I found that a value of eight for the x and y and 234 00:08:27,230 --> 00:08:28,820 a value of four for the z 235 00:08:28,820 --> 00:08:30,850 looks pretty good for this scene. 236 00:08:30,845 --> 00:08:33,115 So now that we've done that, let's jump back over to 237 00:08:33,110 --> 00:08:36,520 the EV settings and then click on bake indirect lighting. 238 00:08:36,515 --> 00:08:38,875 And that will make the entire scene have bound sliding. 239 00:08:38,870 --> 00:08:40,870 And it will look a really nice. 240 00:08:40,865 --> 00:08:43,645 Now that the indirect lighting has finished baking, 241 00:08:43,640 --> 00:08:46,160 Let's press Z and go into rendered view. 242 00:08:46,160 --> 00:08:48,290 As you can see, there is no lightweight 243 00:08:48,290 --> 00:08:50,330 anywhere and it is looking much better. 244 00:08:50,330 --> 00:08:51,860 The interior now has bounced 245 00:08:51,860 --> 00:08:53,680 lighting and it looks really nice. 246 00:08:53,675 --> 00:08:56,015 It almost looks good as cycles. 247 00:08:56,015 --> 00:08:58,855 So now that we've added all of the indirect lighting, 248 00:08:58,850 --> 00:09:01,040 I think we are ready to render this out. 249 00:09:01,040 --> 00:09:02,420 So for the render samples, 250 00:09:02,420 --> 00:09:05,390 I'm going to go up to a value of 128. 251 00:09:05,390 --> 00:09:07,760 I don't think you need to go any higher than that. 252 00:09:07,760 --> 00:09:10,430 And make sure you save your project once again, 253 00:09:10,430 --> 00:09:11,960 then you can go over to render 254 00:09:11,960 --> 00:09:14,150 and then click on Render Image. 255 00:09:14,150 --> 00:09:16,130 This might take a minute or two 256 00:09:16,130 --> 00:09:17,930 depending on how fast your computer is. 257 00:09:17,930 --> 00:09:19,180 But once it's done rendering, 258 00:09:19,175 --> 00:09:21,775 it'll take those composite knows that we've 259 00:09:21,770 --> 00:09:23,270 created in the last section 260 00:09:23,270 --> 00:09:25,600 and then apply it to the EV render. 261 00:09:25,595 --> 00:09:27,625 And the rotor has finished and it 262 00:09:27,620 --> 00:09:29,390 only took about 20 seconds. 263 00:09:29,390 --> 00:09:32,000 And as you can see, it does look really nice. 264 00:09:32,000 --> 00:09:34,130 If you want to change how the render looks, 265 00:09:34,130 --> 00:09:36,020 you can exit out of this window and go over 266 00:09:36,020 --> 00:09:38,450 to the compositing space right here. 267 00:09:38,450 --> 00:09:40,850 We don't really need a lot of these nodes. 268 00:09:40,850 --> 00:09:41,930 Like for example, we don't need 269 00:09:41,930 --> 00:09:43,630 a gamma nodes, we can get rid of that. 270 00:09:43,625 --> 00:09:45,265 We'll plug it into here. 271 00:09:45,260 --> 00:09:47,780 And then you can change the color if you wanted to. 272 00:09:47,780 --> 00:09:48,950 So if you wanted the shadows to 273 00:09:48,950 --> 00:09:50,270 be just a tiny bit brighter, 274 00:09:50,270 --> 00:09:51,650 you can drive that up. 275 00:09:51,650 --> 00:09:53,300 If the highlights are too bright, 276 00:09:53,300 --> 00:09:55,940 you can drive that down and play around with the nodes 277 00:09:55,940 --> 00:09:59,150 just like you did before in the cycles version. 278 00:09:59,150 --> 00:10:01,450 Once you are happy with the nodes that you've set up, 279 00:10:01,445 --> 00:10:04,325 you can press F 11 to bring back your scene, 280 00:10:04,325 --> 00:10:05,935 come over to here and type in 281 00:10:05,930 --> 00:10:07,970 viewer and select the viewer node. 282 00:10:07,970 --> 00:10:10,480 And then you can press Shift Alt S to save it. 283 00:10:10,475 --> 00:10:13,465 Or you can go over to image and click on Save As, 284 00:10:13,460 --> 00:10:15,200 and then name it however you want. 285 00:10:15,200 --> 00:10:18,350 I'm going to call it AB Tutorial 2, 286 00:10:18,350 --> 00:10:20,720 and then I'll click on Save As. 287 00:10:20,720 --> 00:10:22,400 There we go. We've now rendered 288 00:10:22,400 --> 00:10:24,610 arsine using the EV Render Engine. 289 00:10:24,605 --> 00:10:26,425 Thank you very much for watching this tutorial 290 00:10:26,420 --> 00:10:28,220 if you created your own, I'd love to see it. 291 00:10:28,220 --> 00:10:29,300 So make sure to post it in 292 00:10:29,300 --> 00:10:31,510 the assignments or the projects. 293 00:10:31,505 --> 00:10:32,965 Now just for fun, 294 00:10:32,960 --> 00:10:34,610 here's a comparison with the EV 295 00:10:34,610 --> 00:10:37,100 render engine and the Cycles Render Engine. 296 00:10:37,100 --> 00:10:38,570 You can take a look at these and see 297 00:10:38,570 --> 00:10:41,150 the differences and find the one that you like. 298 00:10:41,150 --> 00:10:43,550 As you can see, they both look really nice. 299 00:10:43,550 --> 00:10:44,750 I think these Cycles render 300 00:10:44,750 --> 00:10:46,250 engine looks a little bit better. 301 00:10:46,250 --> 00:10:48,050 It looks a little bit more realistic. 302 00:10:48,050 --> 00:10:49,610 But the IV, your render engine, 303 00:10:49,610 --> 00:10:50,930 the render time only took 304 00:10:50,930 --> 00:10:54,440 20 seconds and it still looks really good. 305 00:10:54,440 --> 00:10:56,450 So they both have their strengths and 306 00:10:56,450 --> 00:10:58,030 weaknesses, but there it is. 307 00:10:58,025 --> 00:10:59,525 That's gonna do it for this section. 308 00:10:59,525 --> 00:11:00,865 Thank you again for watching and 309 00:11:00,860 --> 00:11:03,240 I'll see you in the next one.
